RAILROAD-SWITCH CHAIR.

SPECIFICATION forming part of Letters Patent No. 317,042, dated May 5, 1885.

Application filed May 17, 1884. (No model.)

To all whom it may concern:

Be it known that I, DANIEL SULLIVAN, a citizen of the United States, residing at Sparta, in the county of Monroe and State of Wisconsin, have invented a new and useful Bailroad-Switch Chair, of which the following is a specification.

My invention has for its objects, first, the substitution of one continuous chair for the two now in use; second, to decrease the liability of the breaking separate cast-iron chairs by the substitutionof acontinuous chair from rail to rail; third, to thereby maintain more perfectly the level of both rails, and thereby decrease the jar consequent upon any unevenness; fourth, to facilitate the throwing of the movable rail; fifth, its increased adaptability to any number of side tracks. I attain these obj ectsby the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a three-throw switch ,with continuous chair, as seen from above;

Fig. 2, a side view of the same, showing the construction of the chair.

Similar letters refer to similar parts throughout the views.

In Fig. 1, A A A represent the chair. It is made by firmly mounting upon the switchtie three rails, ten feet in length, (dividing a thirty-foot rail into three equal parts,) in such manner as is represented in crosssection in Fig. 2, AA. Ithus secure a firm fiat surface, ten feet long and eight inches in width, upon which rails F G H and F G H firmly rest,and

switch-rails D D can be easily made to slide by moving switch-bar E E. The chair is spiked to the switch-tie B B, and is held together by bolts 0 c, 850., making ita solid mass. On the outer sides of the outer rails are fastened splices I I by the bolts J J, which pass through the ends of the immovable rails, and

the chair, and partly on the inverted rail N 0.

2. The movable rails D and D rest upon rail No. 3 of the chair, and partly on inverted rail No. 2. Thus my invention is adapted to a switch of any number of throws without increasing the liability of breaking.

In the chairs now in use the wear of the movable rail causes frequent breaking.

In Fig. 2, B is switch-tie; A A A, transverse section of chair, showing relative position of the three rails. c is bolt fastening three rails; I, plate on outer rail; J, end of bolt fastening immovable rails. In combination with the continuous switch-chair formed of the two outer and the intermediate inverted rail-sections there must be a sleeper supporting said chair, depressed and located on a plane below the adjacent track ties or sleeper.

What I claimas my invention, and desire Letters Patent for, is-

1. The herein-described continuous chair for railway-switches, consisting of the two outer lengths and the intermediate inverted length of railway-iron secured together by any suitable means, substantially as set forth.

2. In combination with the continuous switch-chair formed of the two outer and the intermediate inverted rail-sections, the depressed sleeper supporting said chair, said sleeper being located on a plane below the adjacent track ties or sleeper, all substantially as set forth.
